Abstract
Effective temperatures for nine giant stars are derived from recent di ameter determinations at 2.2 mu m with the FLUOR beam combiner on the IOTA interferometer. A good overlap with previous studies for stars ea rlier than M6 is verified. The present paper extends the temperature s cale of giant stars based on direct measurements to types between M6 a nd M8.
